TOOL FOR REIVIOVING CLAMPS FROM BATTERY POSTS.

Application filed- April 7,

This invention relates to a'tool designed particularly for removing clamps from the terminal posts of batteries.

An important object of the invention is to provide a tool of this nature which is exceedingly compact and convenient so that it may be utilized in the usual close quarters provided about a storage battery, for instance, in an automobile, therebyafli'ording easy access to theclamp to be removed and allowing the operation of removal to be accomplished with the expenditure of a minimum amount of labor.

Another very important object of the invention resides in the provision of a tool of this nature with an exceedingly simple construction, one which is thoroughly efficient and reliable in operation, strong and durable, inexpensive to manufacture, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in View as will appear as the description proceeds, the invention resides in oertain novel features of construction, and in the combination and arrangement'of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is an elevation of the tool embodying the features of my invention,

Fig. 2 is a fragmentary detail section taken substantially on the line 22 of Fig. 1, and

Fig. 3 is a transverse section taken substantially on the line 3-3 of Fig. 1.

Referring to the drawings in detail, it will be seen that numerals 5 designate a pair of jaws which are formed integrally on handles 6. Portions of the handles 6 are formed with openings 7, said portions being pivoted together by pins, rivets or the like 8 which are attached to a frame 9 which is preferably rectangular orsquare in formation, and is disposed within one of the openings 7 as is clearly illustrated in Fig. 3. A rack bar 10 is slidable through the frame 9. A frame 11 is disposed over the rack bar and has cars 12 on opposite sides thereof which are pivotally engaged with links 13. These links 13 are pivotally engaged with ears 14: projecting from intermediate portions of the handles 6. I p

A pin 15 pierces an opening in the frame 11 for engaging the teeth of the rack bar 10. A plate 17 is provided with three branches 1 9 2 Serial No. 106,349

and 19 having therein slots 20 and 21 respectively. The branches 18 extend transversely across the intermediate portions of the handles 6 and pins 22 extending from the handles 6 pierce the slots 20. The pin 15 pierces the slot 21, it being noted that the branch 19 extends downwardly alongside of the rack bar.

The manner of using the tool is almost apparent from Fig. 1. The jaws 5 are set by the handle'6 to engage under'a clamp C on the post P of the battery B, the pin 15 being removed and the rack bar 10 adjusted so that the end between the jaws 5 rest on the top of the post P. The pin 15 is then again engaged with the teeth of the rack bar. When the handles 6 are grasped with one hand and pushed toward each other, the jaws '5 not only tighten about the clamp C, but the rack bar is pushed downwardly through the frame 9, thereby causing the easy removal of the clamp C. The plate 17 steadies the rack bar and prevents it from moving from side to side, that is, prevents it from swinging out of the plane of the handles 6.

Vith this tool, it will be seen that the clamps C may be readily and easily removed from the post P with little or no efiort and the tool is exceedingly handy because of its compactness, and is therefore conveniently used in close quarters as is desirable because of the rather inconvenient places in which batteries are usually placed. 7

The present embodiment of the invention has been disclosed indetail because in actual practice, it attains the features of advantage enumerated as desirable in the statement of theinvention and the above description. It will be apparent, however, that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed, or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is i j 1. A tool of the class described including a pair of jaws merging into handles, said handles being provided with openings, one opening receiving the portion of the other handle having the opening, elements pivoting thehandles together, a frame attached to said. elements and disposed; in one of the openings, a rack bar slidable through the frame, a second frame on the rack bar, links betWeen the second franie and the handle,

and a pin piercing the secondframe for engaging the rack bar.

2. A tool of the class described including a pair of jaws merging into handles, said handles being provided With openings, one opening receiving the portion of the other handle having the opening, elements pivoting the'handles together, a frame attached to said elements and disposed in one ofthe openings, a rack bar slidable through the frame, a second frame on the rack bar, links between the second frame and the handle, a pin piercing the second frame for engaging the rack bar, a platehaving three branches provided With slots, the slot of one branch receiving said pins, and pins extending from the handles and piercing the other slots.

In testnnony whereof I affix my signature.
